ADVERTISING DEVICE.-

SPEGIFICATION formingpart of Letters Patent No. 439,329, dated October 28, 1890.

Serial No. 353,704. (No model.)

To all whom it may concern.-

Be it known that I, HOWARD AUSTIN SNY- DER, a citizen of the United States, residing of Pennsylvania, have invented a new and useful Improvement in Advertising Devices, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of improvements in the class of advertising devices for which Letters Patent No. 428,423 were granted to me on the 20th day of May, 1890.

The novel features will be hereinafter fully set forth and definitely claimed.

Figure 1 represents a perspective view of a portion of an advertising device embodying my invention. Fig. Q'represents a side elevation thereof.

Similar letters of reference indicate corresponding parts in the two figures.

- Referring to the drawings, A designates a shaft, which is suitably mounted and receives power from any desired source.

B designates cards or leaves which are fitted in frames 0, to whose cross-pieces are attached pawls D, the latter engaging with ratchets Eon the shaft A. The frames 0 are freely connected with the shaft A by means of loops or eyes F, which are secured to the inner ends of the frames and loosely encircle said shaft. Abox or casing G is provided, the same having an open front, whereby the faces of the cards or leaves B may be presented thereat.

The operation is as follows: Power is communicated to the shaft A, and as the ratchets' E rotate therewith the engaging-pawls D carry the leaves 13 upward, the direction of motion being shown by the arrow, Fig. 2. When a leaf reaches the top and passes the center, it drops or falls, whereby an advertisement is presented, the same being complete in itself or constituting part of the advertisement of the next card placed in uppermost position. The leaves continue to be raised, and are successively dropped as long as the shaft A continues its motion.

The frames 0 are preferably constructed of metal and are of the form of channels, so that the leaves may be readily inserted and held thereinto and removed when desired.

Suitable springs may be applied to the dogs or pawls D, or stops connected to the side pieces of the frames, in order to limit the outward motion of said pawls, so as to prevent actual disengagement of the same from the ratchets.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an advertising device, a rotative shaft carrying a ratchet which engages with apawl connected with a card or leaf, the latter being attached to said shaft, the parts named being combined substantially as described.

2. An advertising device consisting of a rotative shaft, a ratchet secured thereto, a

leaf freely mounted on said shaft, and apawlwhich is attached to said leaf and is engaged by said ratchet, said parts being combined substantially as described.

3. In an advertising device, a channeled card or leaf holder or frame provided with a pawl, and a rotative shaft carrying a ratchet which engages wit-h said pawl, the holder being freely connected with the shaft, substantially as described.

4. In an advertising device, a rotative shaft having a ratchet secured thereto, a card or leaf carrying frame provided with a pawl with which said ratchet engages, and loops connected with said frame and freely attached to said shaft, said parts being combined substantially as described, forming an improvement in advertising devices, as stated.
